GRAIN-BINDER ATTACHMENT.

Specicaton of Letters Patent.

Patented Apr. 22, wald..

Application filed February 17, 1919. Serial No. 277,567.

To all whom t may concern:

Be it known that I, HERMAN LAQUA, a citizen of the United States,residing at Zumbro Falls, in the county of Wab asha and State ofMinnesota, have invented certain new and useful Improvements in Grain-Binder Attachments, of which the following is a specication.

The present invention comprehends generally improvements in that classof inven tions known as harvesters and more particularly relates to agrain binder attachment.

It is the primary aim and object of this invention to provide a deviceof the above mentioned character designed to be attached to a grainbinder for holding the grain in position with respect to the knottingand binding mechanism.

More particularly the present invention contemplates the provision of adevice of the above mentioned character wherein there is employed a pairof pivotally and resiliently mounted grain holding arms preferablyassociated with the spring rail of a binder and positioned on oppositesides of the binding and knotting mechanism so as to temporarily holdthe grain back in proper relation to the said mechanism until thecompleted bundles are ready to be discharged from the machine.

Among the other aims and objects of this invention may be recited theprovision of a device of the above mentioned character with a view tocompactness and wherein the number of parts are few, the constructionsimple, the cost of production low and the eliiciency high.

Other objects, as well `as the nature, characteristic features and scopeof this invention will be more readily apparent from the followingdescription taken in connection with the accompanying drawings, andpointed out in the claims, forming a part of this specification.

The invention is clearly illustrated in the accompanying drawings, inwhich Figure 1 is a perspective view showing the grain holding devicesattached to the spring rail and positioned on opposite sides of thelinding and knotting mechanism of the bin- Fig. 2 is an enlarged sideelevational detail of one of the grain holding devices, and

Fig. 3 is a front elevational detail of the same.

Similar characters of reference are employed in all of the abovedescribed views, to indicate corresponding parts.

Referring now, more particularly, to the accompanying drawings there isillustrated a portion of a selfebinder and includes the usual springrail A suitably supported over the deck B of the binder whileoperatively associated with the spring rail and positioned on oppositesides of the binding and knotting mechanism C are the improved grainholders indicated generally by the letter D designed for temporarilyholding the grain back in proper relation to the binding and knottingmechanism until the completed bundles are ready to be discharged fromthe machine.

ln the present instance each grain holding device may be said to consistof an attaching arm l having an attaching portion 2 secured to thespring rail as by suitable fasteners 3 provided at its inner terminalwith a depending flange d which in addition to bracing the attachingportion 2 acts to accomplish another purpose as will hereinafter appear.The main portion of the attaching bracket preferably is extendedupwardly at its inclination and of course rearwardly from the springrail. Swingably connected to the outer end of the bracket 1 is one ofthe sectional holding arms generally designated by the numeral 5. lnreducing this feature of the invention to practice, the inner sectionmay be said to consist of spaced bars 6 mounted upon opposite sides andat the inner end of the outer section in the form of an elongated bar 7preferably by means of a nut and bolt arrangement 8. A similar fasteningmeans 9 serves to pivotally conneet the bars 6 on opposite sides of theouter portion of the attaching bracket l. The nut and bolt `arrangement9 serves merely as pivotal means for the arm 5 but the nut and boltarrangement 8 acts also as a means for clamping the outer section ordeck engaging bar 7 between the inner section or the relatively shortspaced bar 6 and in various positions of angular adjustment.

ln order to yieldin gly hold the deck engaging bar 7 in engagement withthe deck B of the binder, resilient means such as a coiled contractilespring Il0 is employed, the outer end being connected to an eye-bolt l1carried by the bar 7 while the inner end terminates in a ring or loop l2which is engaged with the depending liange a of the attaching bracket.

In use, it is apparent from the brief d escription that the pivotallymounted grain holding or retarding arm 5 being held in yieldingengagement With the deck B of the binder by the springs 10 will act totemporarily hold or retard thev grain in proper relation to the bindingand knotting mecha nism C iuitil the completed bundles are ready to 'bedischarged from the machine, the Weight of the bundles of courseovercoming the tension of the spring l so that the armr 5 Will raiseupwardly allowing the bundles to pass down the deck or platform B as isapparent. At times it is desirable to arrange the arm in an inactiveposition and in such event it is only necessary to swing the sameupwardly beyond the center whereupon the springs will become inactiveand the arms will rest on the Windshield E of the binder as is apparent.

It is believed in view of the foregoing description that a furtherdetailed description of the operation of the invention is entirelyunnecessary, likewise, it is believed that the advantages of theinvention will be readily apparent.

Still further embodiments of the invention than those herein especiallydefined may be resorted to as conditions or preference may dictate, asmay be in keeping with the hereto appended claims.

Havingthus fully described the invention what is claimed as new, anddesired to be secured by Letters Patent, is

1. A grain holding attachment for selfbinders including a spring railenga-ging and supporting bracket, a sectional arm com- `posed of aninner section and an outer section, means for pivotally connecting theinner end of the inner section to the bracket, means for clamping theoutersections in various positions of angular adjustment with respect tothe inner section, and resilient means between the outer section of thearm and the ,bracket for yieldingly holding the outer section of the armagainst the deck of the binder.

2. A grain holding attachment for binders including a spring railengaging bracket having an attachingV portion and a supporting portionand also formed at its attaching portion With a depending flange, asectional grain holding arm including an inner section consisting ofspaced bars and an outer section in the formV of an elongated bar, meansfor releasably clamping the inner end of the bar between the outerportions oi' the inner spaced bars so that the outer bar will lie invarious positions of angular adjustment relative to the inner bars,means for pivotally connecting the inner bars to the supporting portionsof the bracket and a coiled contractile spring having its respectiveends connected to the outer bar and to the flange on the bracket foryieldingly holding the outer end of the outer bar in engagement With thedeck of the binder.

ln testimony whereof l ax my signature hereto.

HERMAN LAQUA.
